Nesting
• Parallel blocks can be nested.
Example:
Processing Order
The processing order for Parallelize Task processing items is not defined. Do not program a measurement
flow that relies on a specific processing order of Parallelize Task processing items.
Transaction Times
Parallel processing may not be able to reduce transaction times as effectively as expected due to the
processing time of each task, and the number of CPU cores. Before commissioning the system, always
check the transaction time with the actual measurement flow and image.
Inserting Camera Image Input Processing Items
• Do not insert a Camera Image Input processing item inside the range of a Parallelize Task processing
item. To use a different Camera image for a measurement under a Parallelize Task processing item, use
the Camera Switching processing item inside the range of the Parallelize Task processing item.
• When inside the range of a Parallelize Task processing item, do not reference an image that is processed
under a different Parallelize Task processing item.
